Abstract
A new texture analysis approach is applied to the problem of classification of pathological states from electron microscopy images of mouse liver cell nuclei. For each pixel in the image, a region of consistent connected neighbouring pixels is extracted, forming a local texel of pixels belonging to the same gray level population. The geometric properties of each texel is described by invariant moment-based features. A recently developed method for fast and exact computation of Cartesian geometric moments is utilized. Each cell nucleus is characterized by a feature vector, giving the average feature values of both the bright and the dark structures. A leave-one-out classification is performed, using 4 different classes of cells (normal, proliferating, precancer and cancer). The results demonstrate that using gray level connected neighbour structures as texels gives us important information about the chromatin texture of the cell nuclei and thus the pathological state of the cell.
